Description
TECHNICAL FIELD OF THE INVENTION
[0001] The present invention relates to creating a wound opener for
head and neck surgery; more particularly, relates to using an
automatic mechanic wound opener to control the position and size of
a wound for head and neck surgery and to introduce endoscopes or
robotic arms through the wound to evaluate and further treat
lesions of head and neck, where the surgery can be performed
smoothly, the wound size can be reduced, and the wound can be
effectively concealed and become invisible.
DESCRIPTION OF THE RELATED ART
[0002] Head/neck surgery is usually performed by an open operation.
An incision made at head/neck and soft tissues are pulled outwardly
for treating lesions. Hence, the traditional head/neck surgery may
result in an obvious visible wound. Furthermore, the issues
pertinent to postoperative care and cosmetic results of the wound
are also encountered.
[0003] Endoscopes or robotic arms can be used for solving these
problems. During the surgery, an operative space is required to be
created at first for smoothly introducing the endoscopes or robotic
arms to evaluate and further treat lesions. The head and neck of a
human body has many different perplexing soft tissues, like
muscles, nerves, glands and vessels. In addition, head and neck
have smaller spaces than the other parts of the body for
dissection. Until now, no proper wound opener is available for head
and neck surgery when the endoscopes or robotic arms are used. As a
result, the endoscopes or robotic arms cannot be operated easily,
which makes surgical procedures difficult.
[0004] Hence, the prior art does not fulfill all users' requests on
actual use.
SUMMARY OF THE INVENTION
[0005] The main purpose of the present invention is to use a
mechanic wound opener to adjust the position and size of a wound
for introducing endoscopes or robotic arms to evaluate and further
treat lesions of head and neck, where surgery can be performed
smoothly, the wound size can be reduced and the wound can be
effectively concealed and become invisible
[0006] To achieve the above purpose, the present invention is a
device of automatic mechanical wound opener for head and neck
surgery, comprising an operating frame and a wound opener, where
the wound opener is set at an end of the operating frame; the wound
opener comprises a fixed unit and a drawing unit; the drawing unit
is movably located on the fixed unit; the supporting unit comprises
an adjusting base and a vertical rod set on the adjusting base; the
connecting unit comprises a second adjusting base movably set on
the vertical rod and a horizontal rod set on the second adjusting
base; the fixed unit comprises an adjusting unit set at an end of
the horizontal rod and a plurality of moving track rods movably set
in the adjusting unit; the drawing unit includes a blade separately
located at an end of each moving track rod; the vertical adjusting
plate is set on at least one of the moving track rods; one of the
blades is connected to the vertical adjusting plate; the adjusting
unit has a chute to be movably combined with the moving track rods;
and each moving track rod has a locking unit to be movably combined
with one of the blades. Accordingly, a novel device of automatic
mechanical wound opener for head and neck surgery is obtained.

DESCRIPTION OF THE PREFERRED EMBODIMENT
[0013] The following description of the preferred embodiment is
provided to understand the features and the structures of the
present invention.
[0014] Please refer to FIG. 1 to FIG. 5, which are a perspective
view, a side view and a top-down view showing a preferred
embodiment according to the present invention; a perspective view
showing the wound opener; and a view showing a state of use of the
preferred embodiment. As shown in the figures, the present
invention is a device of automatic mechanical wound opener for head
and neck surgery, comprising an operating frame 1 and a wound
opener 2.
[0015] The operating frame 1 comprises a supporting unit 11; and a
connecting unit 12 movably connected with the supporting unit 11,
where the supporting unit 11 comprises a first adjusting base 111
and a vertical rod 112 set on the first adjusting base 111; and the
connecting unit 12 comprises a second adjusting base 121 movably
set on the vertical rod 112 and a horizontal rod 122 set on the
second adjusting base 121.
[0016] The wound opener 2 is set at an end of the horizontal rod
122 of the connecting unit 12 of the operating frame 1. Therein,
the wound opener 2 comprises a fixed unit 21 and a drawing unit 22
movably set on the fixed unit 21; the fixed unit 21 comprises an
adjusting unit 211 set at an end of the horizontal rod 122 and a
plurality of moving track rods 212 movably set in the adjusting
unit 211; the drawing unit 22 includes a blade 221 separately set
at an end of each one of the moving track rods 212; the adjusting
unit 211 is set with a chute 213 for movably combining the moving
track rods 212; each moving track rod 212 is separately set with a
locking unit 214 for movably combined with the blade 221; a
vertical adjusting plate 215 is set on at least one moving track
rod 212 (at an upper side); and, one blade 221 (the blade at the
upper side) is connected with the vertical adjusting plate 215.
[0017] Thus, a novel device of automatic mechanical wound opener of
head/neck soft tissues is obtained.
[0018] Using the present invention, the first adjusting base 111 of
the supporting unit 11 of the operating frame 1 is set at a side of
an operating bed 3 to establish the wound opener 2. A height of the
vertical rod 112 and a fixed position of the vertical rod 112
corresponding to the operating bed 3 are adjusted before setting
the first adjusting base 111. In addition, an operational length of
the horizontal rod 122 is adjusted by the second adjusting base 121
before being fixed for adjusting the wound opener 2 according to a
patient's position. Thus, the operating frame 1 and the wound
opener 2 are fixed on the operating bed 3 for preventing sway
during surgery.
[0019] After the supporting unit 11 and the connecting unit of the
operating frame 1 are adjusted to proper positions, the drawing
unit 22 of the wound opener 2 is set at a wound on skin of the
patient for surgery and each blade 221 is introduced into the wound
from outward to inward for hooking head/neck soft tissues at upper
and lower sides. The blade 221 brings the moving track rod 212 to
move along the chute 213 of the adjusting unit 211 as the blade 221
moves; or, the vertical adjusting plate 215 is used to adjust the
position of the blade 221 at the upper side. After each blade 221
is moved to a fixed position, the adjusting unit 211 is fixed to
decide wound size, where each blade 221 is adjusted to create a
sufficient operative space and to be fixed for maintaining the
space. Thus, each blade 221 is used to create the operative space,
where endoscopes or robotic arms can be smoothly introduced to
evaluate and treat lesions; The wound opener 2 helps operators
(doctors) on head and neck surgeries, where the wound size can be
further reduced and the wound can be effectively concealed.
[0020] During practical use, each blade 221 can be changed based on
different requirement. For changing the blade 221, the locking unit
214 at the end of the moving track rod 212 is removed; then, the
original blade 221 on the moving track rod 212 is taken off; then,
a proper blade is re-set on the moving track rod 212; and, then,
the locking unit 214 is locked at the end of the moving track rod
212. Thus, the blade 221 is changed to meet special needs of
distinct situations.
[0021] To sum up, the present invention is a device of automatic
mechanical wound opener for head and neck surgery, where a mechanic
wound opener is used to adjust position and size of a wound for
introducing endoscopes or robotic arms to evaluate and treat head
and neck lesions; and, thus, the present invention facilitates
surgical procedure, reduces wound size and effectively conceals the
wound to make it become invisible.
[0022] The preferred embodiment herein disclosed is not intended to
unnecessarily limit the scope of the invention. Therefore, simple
modifications or variations belonging to the equivalent of the
scope of the claims and the instructions disclosed herein for a
patent are all within the scope of the present invention.
